According to a recent study of ICMR, several parts of the country have seen a sudden uptick in cold, cough & fever, and is believed to be linked with H3N2 influenza cases. A couple of deaths reported in the country are raising serious concerns. The health ministry has confirmed that the virus is contagious but seasonal.

Hence, having all the information about the virus, symptoms, & risk factors, and treatment options available is essential to take the correct course of action.

So, let’s start with what is an H3N2 influenza virus.

Classified into different subtypes depending on the combination of proteins on the virus surface, H3N2 influenza is not a new virus. It is a respiratory disease that causes several respiratory-related issues among individuals. However, it is a seasonal virus that knocks on the door every year and eventually goes away. The sudden drop in the temperature is the culprit behind the rapid spread. It usually causes a fever that lasts for a few days and causes prolonged cough & cold for up to weeks. The disease is mild but can lead to complications and death if left unaddressed. So, if you or anyone in your known experiencing influenza symptoms, get tested in time to control the condition.

Now the question is how to identify its early symptoms, as most of them are similar to other common conditions. The answer is right here;

Severe H3N2 Influenza Symptoms To Look Out For:

  • Difficulty Breathing: It is a respiratory infection, so one of the most common symptoms of the H3N2 influenza virus is shortness of breath. The onset of pneumonia may start respiratory complications in patients.
  • Nausea & Vomiting: Another common symptom an infected individual might experience is severe or persistent vomiting.
  • Body Aches: If you are experiencing unusual aches in different body signs coupled with other symptoms, it could be because of the H3N2 influenza. Getting tested in time is essential to identify the virus early and take precautions.
  • Persistent Cough: The virus majorly impacts your respiratory system, causing problems in breathing and a severe cough that lasts up to 3 weeks or so.
  • Headache: Not just body aches, frequent headaches you are experiencing these days may also be a sign that something in your body needs your attention.
  • Diarrhea: People infected with H3N2 influenza also complain about diarrhea and dehydration.
  • High Fever: High fever persisting for more than three days is another common sign indicating the H3N2 influenza virus and calls for immediate testing to avoid severities.
  • Extreme Fatigue: Constant lethargy is another common sign indicating to H3N2 influenza virus. It is said that an infected individual is more likely to experience exhaustion or weakness.
  • Sudden Chest Pain: Unusual pain or pressure in the chest can also be due to respiratory complications caused due to this infection.

Therefore, no matter how small or common the sign you may think it is, do not wait for the disease to take over your health. Seek medical attention before the eleventh hour to ease the symptoms, prevent complications, and speed up recovery.
